The works this atlas cites as evidence for its facts and prose, spanning encyclopedia articles, academic references, open educational references, reference websites and this atlas's own internal register, each carrying the locator and quotation that ties a specific claim back to the page it came from. Belongs here: a citable published work or page this atlas draws facts from. Does not belong here: the subject of a citation, such as a scholar who wrote a cited work, who is documented as a theorist entity in this atlas's own right rather than filed here as a source.
